It is "clearly illustrated thata' spring-:25

That is to say, if thefilling, piece of the first elevatorisinapositi'on'notto sup- 7 port thefirst elevator when display casting is done, the assembling elevator"ca-nnot'be' raised until the duplex rail is'manually withdrawn fromi-anauxiliary position,"or untilv the; filling piecehas been actuatedmanually and thrown over into the position, shown in 'fulllines in'Figure In the emannerlhere inset forth,gI am able to instantly causethe f other of the tw above stated operationshas c'taken place,-'and atthat time only is it possible to send'a composed line throughthe machine. 1

In Figure 4 of the drawings first elelongerian obstruction in thevertical path of assembling elevator tolock until-one or the,

fvator filling piece has beenturned to cam the I "lever 14 so thatthelug17 thereof presses against the'tail piece of the lever 18, thus"turning, the latter in a direction oontraryto the normal tension exertedthereupon by the Iaforest'ated spring 25. In this movementof the lever18, the normal'position ofthe dog 21 "shifts from a-positio'n insuperposed relation Ito the portion A of the duplex rail to the;

position -B ofsaidrail, where it is'now no movement of theassemblingelevator. In I consequence thereof it manifestly followsthatthe elevator may nowproceed upward.

' When'it is intendedthat the matrices shall be maintainedat a positionI at'the lower level of the assembling elevator, and'thusg sent throughthe machine, it will be necessary that I a eia-37o theduplex rail befirst manually withdrawn,

at which time the dog 21 iscleared from the i dotted lines andthe pathof the screw relative p to tho filling piece is indicated-by the dotanddashline's'L.

The dog21, because of the relative arrangement of qpartsland thenovelcombinationot elements lierein-recitedfis thus positioned at thelower end of the intermediate'transfer channel,with the spring '24normally urging the lower 'end ,of- 'said dog to'a position slightlyinto the adjacent end of the assemblingelevator and insuperposedrelation to Q a said duplex rail. The dog'therefore simply i overliesthe duplex rail normally and serves to blockor obstruct the path ofmovement of the assembling mechanism. Through this novel manner ofco-ordinating'the parts and the machine .in double black position I ptoo, upontthe novel combinatlon of a few mov combining same forrelative" coaction I am I able to entlrely eliminate interference w1ththe intended position of theiline' of matrices such as would causesameto besent through This is primarily because ofthe fact that din.-

ing theraising of the assembling elevator the operator, no part of mydevice is brought the duplex rail that could possibly result inderangement in the [intended order-of the j into frictionallcontactwithany portion of .matrices V I mal or assembling position, again, the"dog,

the duplex rail be withdrawn manuallv and positioned out of the can besent through the machine in either normal or auxiliary positions, as maydepend th ere beingnorm'ally slight clearance between the upper face ofthe latter and the 'lower' blockingworf obstructing end 0f the dogpno 1visible friction orend thrust is s'et'up against 1 the. duplex rail orbetween the latter andeny" path ofgthe lower extremitv of thedog 21. V

My device providesmeanswherebylines I amv broadlyflc' ncerned the novel{combination of elements which constitutemy part of the device thatcould possibly result in disturbing the composed line'duringinp tendedupward movement of the assembling elevator. r

device or mechanism, ,the y-sa'me' consisting} norma lly, occupy aposition a in 1 the assembling elevator'where it will obstruct upwardmovement of said elevator, but which at no principally ofa dog or otherblocking device i that may be the mechanical equivalent there: ;ofstructurally aridfunctionally, that will up in a fillingpieceof thefirstelev'ato'r'andwhereby, without disturbing the fillingipiece of saidfirstelevator, the 'doglwill-be made" to clear itself from the duplexrail whenthe'i latter is manually withdrawn; I lay stress,

In

consequence "thereof, it will be appreciated that provision is hereinmadexfor limiting the movement of the cam-surface lG relat veQ to theeffective path of movement of the said blade 65, thus positivelyinsuringoperat' on of the lever 14 at each impulse from the said iblade. I
